HPEiLOCmdlets 4.0.0.0, Get-HPEiLOHealthSummary produces error on Ubuntu system

[cjs1976]

Hi team,

I am working with the "Scripting Tools for Windows PowerShell: iLO cmdlets" (https://support.hpe.com/connect/s/softwaredetails?language=en_US&softwareId=MTX_bb648dcdf9b9424b8ffdd96d53&tab=revisionHistory) under Windows for qite some time.

It worked great. With the last iLO 5 versions the issues startet. I found some complains over a Google search, but no solution.

*************
ERROR-Message
*************
Cannot deserialize the current JSON array (e.g. [1,2,3]) into type
'HPE.iLO.Communication.Redfish.DataEntity.OData' because the type requires a JSON object (e.g. {"name":"value"}) to
deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to
an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be
deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a
JSON array.
*************

A couple of weeks ago new HPEiLOCmdlets 4.0.0.0 were released and also new iLO versions, so I started a new try on a test system.

For the Test, I don't use Windows, I use Ubuntu 22.04, PowerShell 7.3.4 and HPEiLOCmdlets 4.0.0.0 (same issue with 3.3.0.0).

I create the connection: $connection = Connect-HPEiLO -Address $iloIp -Username $iloUser -Password $iloPassword -DisableCertificateAuthentication

Everything ok.

I try to get the HealthSummary

$result = Get-HPEiLOHealthSummary -Connection $connection

*************
ERROR-Message
*************
GenericArguments[0], 'HPE.iLO.Communication.RIBCL.DataEntity.TEMP', on 'T MaxInteger[T](System.Collections.Generic.IEnumerable`1[T])' violates the constraint of type 'T'.
*************

At least it's a new error

Has by chance someone an Idea/a Solution?

Thanks,
Christian.

Greetings!

Is the OS running latest version of AMS? As I believe AMS populates this data so it must be running in the server OS.

As you mentioned that the issue started after updating iLO version. Could you confirm on which iLO version was it working?
Did you get a chance to downgrade iLO to working version on one of the servers for testing and check the results?

On my environment (Windows 10 + Powershell 7.3 + HPEiLOCmdlets 4.0.0.0), Get-HPEiLOHealthSummary usually worked well with iLO 5 with 2.78 version.

But after upgrade the machine's iLO 5 to 2.91 version, it start not working.

Recently, I upgraded HPEiLOCmdlets to 4.3.0.0, the issue still happen.  the issue is not still fixed in HPEiLOCmdlets  4.3.0.0.

Could anybody in HPE have a look on this issue on priority?  we are depending on this function to run daily health check on a lot of HPE ProLiant servers.
